cannot change region for billing address on xbox360 console

https://beta.support.xbox.com/help/subscriptions-billing/browse use this link to get help with billing issues. I hope this helps.

i changed the region on xbox one console and in my account setting (i have migrated), also billing address is for the region i choose, still the same message "Sorry

Your purchase cannot be completed at this time. Please try again."

G'day Sandreas! Just to make sure I understand, are you still seeing a US billing page after migrating your account's region

with the steps here? Once the account is fully migrated to the UK, you should have the option of using UK billing information.

Hey there, jivs! I'm very sorry to see that you are unable to change your billing address! Mauritius isn't one of the countries supported by Xbox Live. For a full list of those countries, you can check out our
Xbox Live Countries page. We are always looking to expand our service, though, so please be sure to get your voice heard on our
Feedback site about this!

If you are unable to
change your Xbox Billing Information following the steps on that page, then I do not think it will be possible to change it to your region until your region is supported.

I hope that helps you out! Please do post back if you have any further questions.

wait your in Ecuador but your billing address is USA that would be why you cannot download certain stuff as a lot of content is region locked. the regions of your account, console, and physical address have to be all the same or you will run into errors.
there is no way to force it to work.
